DRINK MIXER.

Application led March 8, 1922. Serial No. 541,910.

To all lwhom it may concern.'

Be it known that I, RAYMOND B. GIL- oHnIs'r, a citizen of the United States, and a resident of Newark, in the county of Essex 6 and State of New Jersey, have invented certain new and useful Improvements in Drink Mixers, of which the following isfa full, clear, and exact description.

The invention relates tol drink mixers. In machines for this purpose, the liquid constituents of the drink to be mixed are usually poured into a receptacle which is generally designated a shaker, from many different containers disposed away from the mixer. The receptacle with these constituents therein is brought to the mixer and placed in operative relation thereto and is removed from the machine after each mixing operation to discharge its contents. 20. This is rendered necessary, because `lso many dierent ingredients and flavors are used in making drinks that they are, in nearly all cases, mixed individually. It is usually necessary to run the agitator for a considerable period to properly blend or mix the constituents and, therefore, itis desirable that provision be made for retainingthe receptacle and agitator in operative relation to permit the dispenser to perform other" duties during the mixing operation. In drink mixing, it thus becomes necessary to frequently place the receptacle, containing the constituents, into cooperative relation to the agitator and to withdraw it from the machine to discharge its contents and cleanse thel receptacle between mixing op-Y erations. Y

A desideratum in this art is to expedite and simplify the operationsl necessary to bring the receptacle and agitator into cooperative rclation, to maintain them in such relation, in starting and stopping of the motor and the removal of the receptacle. Heretofore, in machines whereof I am aware excepting those exhibited by me in pending applications for patents, it has been necessary in'their use to manually manipulate the receptacle into operative position and withdraw it therefrom and to additionally perform some separate step or operation, such as lowering the motor and agitator together, or shifting the agitator and its 'shaft into the receptacle and relatively to the motor, or raising and locking a receptacle support to establish and maintain cooperative relation of the receptacle and agitator or to control the operation of the machine. Another desideratum in this art is to simplify ther machine by dispensing with movable connections in and' for the mechamsm for driving the agitator.

One object of the present invention is to provide an improved drink mixer'in which these additional operations or steps are dispensed with and in which manual shift of the receptacle is utilized to completely control the operation of the machine and the securing of the receptacle and the agitator 1n cooperative relation. By dispensing with the necessity of these additional steps or 7 operations, the time of the dispenser in per- -forming them is saved and the service isv improved.

Another object of the invention is to provide a receptacle controlled machine which 75 1s equi ped so vthat the rece tacle can be manipu ated to control its loc ing into 'op-N erative position around the agitator, its release for withdrawal, and the starting and stopping of the motor. s

Another object of the invention is to provide a machine of this t pe in which movable connections in an for vthe driving meclhanism for the agitator are dispensed wit u Another object of the invention is to provide a machine lwhich is simple in construction, which ma -be easily and readily 0perated and which is elicient in operation.

Other objects of the invention will more W tfully appear from the following descripion.

The invention consists in the several novel features hereinafter set forth land more particularly dened by claims at the conclul' sion hereof.

In thedrawings: Fig 1 is a vertical section of a machine embodying the. invention, parts being shown in elevation. Fig. 2 is a rear elevation. Fig. 3 is a horizontal section 10i@ on line 3-3 of Fig. 1. Fig. 4 is a detail of the upper portion of the slot in the supporting standard.

The invention is exemplified in a machine. comprising an electric motor which is se- 1w cured to the upper end of a supporting standard 9. The atter is ri 'dly secured to a base 10 by a bolt 10, whic is adapted to rest on a counter or table. A n agitator shaft 1-1u projecting .downwardly from, and secured to,'-the rotor of the motor' 8,'is pro vided at its lower end withan agitator 12 of suitable construction, aswellunderstood in the art. Shaft ll'hasixed relation to the rotor of the motor 8, thus avoiding a sliding connection for permitting the agitator to be raised and lowered into the receptacle 19 which contains the material to be mixed. is sufficient clearance below and' t around the agitator to permit the receptacle to :be placed intol operative position from below and without moving the agitator. The case of motor 8 isvv rigidly secured to the up- .,per endof standardv 9 by screws which l extend thr'oug'h'a block 14. A case 15, containing a snap-switch of usual construction with members connected to control the niotor 8, is iixedlv secured to the block 14 and is provided with a lever 16 which is of the snap-'type and spring-pressed into both of the alternate positions into which it is shifted, as well understood in the art, so that it will remain in one position until it .is reverselyshifted to the other.

The front face'18 of standard 9 is arcuate in cross section, conforming substantially to the peripheryl 'of the receptacle 19 which may, if desired, be provided with upper and lower wear or'reinforcing bands 21, 21a. This arcuate face extends vertically to form a stationary guide on which the receptacle 19 may slide into and out of operative relation with'the agitator 12. Receptacle 19 is provided with a stud which is fixed thereto and projects from the outer side thereof and comprises a shank 23 and an enlarged head 24 adapted to form an interlock with the supporting standard or guide `and lock the receptacle'against forward, backward and lateral movement while the receptacle is "of the shank'23 of the stud into the slot 25 and its removal therefrom. When the stud is raised above the opening 26, it will cause the" receptacle to be locked against horizontal movement in any direction, the head 24 lapping and being confined by the back of the standard -9 and the stud-shank 23 being held against lrearward movement by engagement vby the receptacle with the front face of the standard 9. At its upper end, slot 25 is prolvided with a lateral offset 27 which is adapted'to receive the stud-shank 23 when the receptacle is rotated on its own axis to cause the studto be vertically locked and thus secure the receptaclein cooperative relation to the agitator.

A -lever 29 is pivoted, at 30, to: the Vback of the standard 9, and has a forked upper end 31 adapted to shift the switch-lever .16 from either of its alternative positions to the other. The lower end of this lever is formed with an open ended cam-slot 32 which is normally disposed, as indicated by dotted lines in Fig. 2, so that the head 24 of the upwardly moving stud on the receptacle will enter it and shift the lever in'to position to operate switch-lever 16 to close the circuit for the motor 8 while the vessel is being lifted to its operative position and so that, while the receptacle is being lowered, the head will reversely shift lever 29 to operate switch-lever 16 to stop the motor. 'lhe upper end of the slot 32 is enlarged or out away, as at 33, so that the rotation of the receptacle and movement of the stud to lock the receptacle will not shift the lever and will cause the motor to run while the restandard, then manually lift the receptacle until the stud-shank 23 encounters the upper end of slot 25, and then rotate the receptacle slightly, to position the shank of the stud in the offset 27` of the guide-slot, whereupon,-

the receptacle will be locked so that the agitator will be in operative relation to the receptacle and its contents. During the lifting of the receptacle, it will be manipulated, supported and locked against lateral movement by the guide and stud, and the head 24 will enter slot 22 in lever 29, engage one of its sides and shift said lever into position shown by full lines in Fig. 2. This will shift the switch-lever 16 into position to close the circuit for the motor 18 and cause it to run until the receptacle is removed.

After the mixing operation has been completed, the operator will grasp the receptacle, rotate. it slightly to release the studshank from the offset 27 of slot 25 and lower the receptacle. In lowering the receptacle, the head 24l of the stud will shift lever 29 into position shown by dotted lines in Fig. 2,

so that the upper end of the lever will snap the switch-lever 16 into position to o en the circuit and causeA the motor to stop. urin the lowering movement of the receptacle, 1t will be horizontallyl locked to the guidestandard, so that there will be no danger of striking the receptacle, until the stud passes into the openin 26, whereupon, the receptacle will be ree to be withdrawn and emptied of is mixed contents.

The invention exem lifies a mixing mai i chine in which the relationship of the agitator and motor is substantially fixed and in which the motor is fixed and which is conand out of operative relation to the agitator; in which means is provided to positively guide the receptacle while it is manually supported and being shifted into and out of cooperative relation with the agitator; which is simple in construction; and in which the receptacle becomes locked in and unlocked from its operative position by rotative manipulation of the receptacle itself.
